Scientists have discussed how nanotechnology could impact medicine for years. Or, at least, they have done so in theory. Nanobots could, in theory, perform surgical tasks in a human body; sort of a real version of the 1966 movie, Fantastic Voyage. Nanotechnology could also assist in prosthetics, medical tools and processes. The possibilities are truly endless.

But, some uses of nanotechnology have left the realm of “theory” and moved into that of “reality.” One recent example is an experiment conducted using an injection of magnetic nanoparticles in place of traditional anesthetic for an ankle block. The study was successful, demonstrating that this process does work (at least in rats). By identifying specific areas in which nanotechnology may benefit us, these researchers are helping other scientists refine realistic use of the nanotechnology.
